Abstract : Security is considered to be an important issue in wireless sensor networks.Clustering is an effectual and convenient way to enhance performance of the WSN system. Sensor nodes have limited power, computational capabilities and memory. Cryptography is the most offered security service in WSN. Applying any encryption scheme requires transmission of extra bits, hence extra processing, memory and battery power are needed. For ensuring robust security for the network, the keys are to be managed, revoked, assigned to a new sensor network or renewed. In this paper different cryptographic schemes and their encountered issues are discussed.
